Problems solved by technology

[0002] At present, most of the sand supply devices commonly used in the water jet industry adopt the water jet self-priming method, that is, the suction generated by the high-pressure water jet is used to suck the sand. When the high-pressure and high-speed water jet is sprayed, a negative pressure will be generated near the water flow. Inhalation of sand, this kind of sand supply device is limited by the structure, often has the disadvantages of small sand volume, difficult adjustment, easy water return, etc., which makes it difficult to improve the cutting efficiency of the waterjet

Abstract

The invention discloses a sand supply device for a waterjet. The sand supply device comprises a sand supply main body, wherein a sand storage bin is arranged in the sand supply main body; a sand inlet communicated with the sand storage bin is formed at the upper end of the sand supply main body; a sand discharge groove communicated with the sand storage bin is formed at the lower end of the sand storage main body; a sand supply port is formed at the lower end of the sand supply main body; two ends of the sand supply port are respectively communicated with the sand storage bin and the sand discharge groove; a pneumatic valve capable of opening and closing the sand supply port is arranged in the sand storage bin; and a sand supply flow regulating piece which can adjust the size of the sand discharge groove is mounted at the lower end of the sand supply main body. The sand discharge quantity of the sand supply device for the waterjet is adjustable, so that the cutting efficiency of the waterjet can be guaranteed.

Description

technical field [0001] The invention relates to a sand supply device, in particular to a water jet sand supply device. Background technique [0002] At present, most of the sand supply devices commonly used in the water jet industry adopt the water jet self-priming method, that is, the suction generated by the high-pressure water jet is used to suck the sand. When the high-pressure and high-speed water jet is sprayed, a negative pressure will be generated near the water flow. Inhaling sand, this kind of sand supply device is limited by the structure, often has the disadvantages of small sand volume, difficult adjustment, easy water return, etc., which makes it difficult to improve the cutting efficiency of the water jet. Contents of the invention [0003] The object of the present invention is to provide a water jet sand supply device with adjustable sand output, thereby ensuring the cutting efficiency of the water jet. [0004] In order to achieve the above purpose, the ...
